从Email Activity返回后,Android键盘仍然可见

Question

我有一个在TabHost中运行的Activity(扩展Activity).我从用户操作启动Android电子邮件客户端.如果我点击电子邮件客户端中的"放弃"按钮,电子邮件客户端将退出,但屏幕上的键盘仍然可见.

我的应用程序上没有EditTexts,因此不确定为什么键盘会保持运行状态.我已经尝试了几次迭代,如何在完成活动后移除键盘？但是没有运气.有什么想法吗？

代码示例

package com.test.launchmail;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.view.inputmethod.InputMethodManager;
import android.widget.Toast;

public class myEmail extends Activity
{
    private final String TAG = "** Email **";


    public static void send (Context ctx, String addy, String subject, String body)
    {
        // check to make sure the entry has a phone number
        try
        {
            // use the builtin chooser for users mail app
            Intent sendIntent = new Intent(Intent.ACTION_SEND);
            sendIntent.setType("text/plain");

            sendIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String [] {addy});
            sendIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
            sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, body);
            ctx.startActivity (Intent.createChooser(sendIntent, "Send via which Application?"));

        }
        catch (Exception e) 
        {
            Toast.makeText (ctx, "No activity was found to handle this action",Toast.LENGTH_SHORT).show();
        }
    }


    @Override
    protected void onPostResume()
    {
       // This executes, but keyboard still visible. 
        Log.d ("myEmail", "hiding");
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow (mainApp.tabHost.getCurrentTabView ().getApplicationWindowToken (),imm.HIDE_IMPLICIT_ONLY);

       super.onResume ();
    }
}

尝试将以下内容放入您的清单文件中所需的活动（您不显示键盘的活动）：windowSoftInputMode="stateHidden"
